Unfortunately that won't work, since "note" isn't a grob. Try

 \balloonGrobText #'NoteHead #'(-4 . -4) \markup { "I'm a note" }

In this case, the grob would be Rest:

\balloonGrobText #'Rest #' (-4 . -4) \markup { "I'm a rest" }

In both cases you'll have to place the \balloonGrobText function
before the item (like \once \override).
